mechanism.

Referring. .to the drawings, the numeral '1- designates as an entirety an approximately rectangular casingcomprising side walls 2 and 3fand-abottom wall '4.

Mountedbetweenthe side wallsQ-and 3 adjacent to one end: thereof is, punching mechanism} designated 5 as. an. entirety.

This punching mechanism consists of two rectangular plates 6"and'7 that are secured in-spaced relation to each other by means of-Jbolts Siarranged .adj agent certain of their ends. Tlie-bolts'iS are inserted through the platesfi and'T and lateral'aperturedlugs 9 carried'fupon, the inner faces ofthe side walls, Q a/nd- 3" and have wing nuts 10 Iturned upon" their upper extended terminals. The

wing nuts are positioned upon the outer or'uppei face of the plate 6. The lugs 9 extend laterally from the walls 2 and 3 and engage the under face of the plate 6 adjacent to theinner end thereof. The forward end of the plate 6 is supported upon lugs 11 similar to the ones 9 that are carried upon the side walls 2 and 3. A bplt and nut connectidn 12 for the lugs 11 and plate 6 is provided.

Inserted centrally through the plates and 7 is a vertical pin or shaft-13. This pin or shaft may be formed integral join-carried otherwise by the plate 7 but is sewhich extends upwardly from the upper side thereof in the form of a boss and engages the under or inner face of the plate 6. An annular flange 17 is formed on the under face of the plate 15 and provides a chamber or compartment to receive an expansive spring 18. The spring 18 is mounted upon the pin or shaft13 and at its terminals engages the plates 15 and 7. This spring serves to normally hold the plate 15 in uppermost position upon theshaft 13. The plates 6, 7 and 15 are provided with suitable slots and openings to receive the punches to be later described. Adjacent to the inner ends of the plates 6, 7 and 15 upon one side thereof are formed approximately S-shaped slots '19. The parallel portions 20 and 21 of'each slot are provided with spaced transverse slots 22 while the other parallel portions 23. of each of the slots 19 are provided with right angularly extending slots 24 which are disposed toward the portions 20. These slots 19 are arranged to receive a date punch designated 25 as an entirety. Upon the opposite sides of the plates relative to the slots 19 at the inner.

"ends of the plates are formed longitudinal slots 26. Each of these longitudinal slots is bisected by aplurality of transverse slots 27. The slots 26 and 27 are designed to receive a month punch designated 28 as an entirety. Upon each side of the center of-the designated 30 as an entirety.

plates are rows 'of. circular openings 29, the rows being arranged longitudinally with ref 'spect to the plate, and each opening or aperturehas mounted therein a. transverse punch transverselywith relation to the plates. I

also provide adjacent to the slots 31 of each Pa sho ter Slot 2 disposed in the same plane as the slots 31 "and slightlyspa-ced with relation thereto. The slots 31 and '32 are provided with plurality of spaced right angularly extending slots 33. The slots 31, 32 and 33 are arranged to receive the A. M. and P. 1V1. time punches desig nated 34 and respectively. The outer face of the plate 6' is provided with the names of the transfer points as clearly s en with reference to Fig. 1 in the draw ngs adjacent .to the openings 29. The other necessary characters with relationto the time, date and month are positioned; ad-

jacent to the ends of the shorter slots that are formed in combination with the longer slots.

The punches for the month. date and time consisting of the punches designated'25. 28,

'34 and 35 are similaras to construction.

Each of these punches consists 'o'f. a :punch rod 36 that is positioned with itsjipunchingedge in the slots described in the plate 7. The. punch -rods 36 extend through the plate 15 and are each positioned within a tubular holder 37.. dach of the holders 37 is provided at its uppenend with a shoulder 38 to engage the under face of the plate 6 and a reduced stem 39 that extends stem 39. The stem 39 is preferably screw threaded. Each of the, caps or knobs 40 is provided with a cylindrical body portion 41 I arranged to engage the npper or outer face of the plate 6 upon either side of the slot. The lower edges of the holders 37 engage the upper face of the plate15. The punch rods 36 are slidable within the holders 37. A collar 42 is fixed upon eachrod 36 and engages the under face of the plate 15. A

spring 43 of the expansion helical type is I mounted upon each punch rod.36 and en gages at its terminals the under face of the collar 42 and'inner face of the plate 7. The springs 43 serve to normally hold the punch rods 36 in inoperative or uppermost position. It will be readily seen with reference t ;t he foregoing description and accompany ing drawings that whenfthe plate-15 is deand 18; The plate'l'fi engages the collars 42 on the punch rods' 36and thusmoves the punch rods. downwardly. "The springs: 18 and/13 serve to return the punch 1 The transfer point punches 30 each con sist of 'apunch rode-1 that is carried'b'yth'e" 6. reduced portion 4510f a holder 46. The

A finger piece or knob 48 is the plate 15 forces the plate downwardlyand by so doing operates the other punches described. The downward movement of the transfer point punches provides for I the punching operation of the punch rods 44.

It will be readilyiseen that the operation of all'the punches is-had upon the depressing of any one .of the transfer point punches The several springs used in connection With .the plate 15' and punches serve to return the plate and punches to their normal position. This point is con-- sideredone of the most essential of my in-.

vention.

A rectangular plate having a plurality,of..- openings 51 therein 'is' carried by the bottom plate 4 of the 'c a'sing 1. in parallel spaced 1relation"thereto'a-nd form a compartment'A which is designed to receive the paper .punchings. The forward end of this compartmentA is open and is adapted to be closedby a suitable slide or door designated 52. 'zThe perforations'or openings 51 in the plate 50 areformed in such a Way so to receive the punching ends of the punch rods-f36'and .44. Itwill be readily seen with reference to Fig.9.. in the" drawings that the bottom plate 7 is spaced from the plate 50 throughout the entire length of the plate 7 This provides, for the disposal ofthe' trans fer so that the transfermay be punched as measurin will be later more fully described. The side Walls 2 and 3 are; enlarged at their rear and receiving drum or roller 53. I ,7

A leaf spring 54 is secured to the side have mounted therebetween a transfer roll wall 2 and adjace t end 0f -the drum or roller .53." Thisspr ng serves to 'hold the roller with the transfer roll thereon in, the

A transfer roll- 55 is proper position. 7 mounted upon the drum or roller 53 and adapted to be Wound therefrom over a roller 56 which is mounted upon a shaft 57 that is journaled at its ends in the walls 2 and 3 rearwardly with respect to thedrum or. roller 53.; The transfer roll is taken from the under side of the roll 55 and arranged upwardly over and around the measuring roll 56. The measuring roll 56 of the transfer roll is extended along the upper face of the. plate 50 and between the plate 50 and under face of the plate 7.

A hearing. roller 5 8 is positioned above the center of the measuring roller 57 and adapted to engage the transfer roll as the transfer roll passes over the measuring roll 56. The bearing roller 57, 58 and measurcured at its ends to the trunnions of the roller 58 and to the inner faceof the cover or. lid 59. This spring member'62 serves to hold the roller 58 in bearing engagement with the transfer paper and to force the paper into firm engagement with the mensuring roll 56.

As, a .means for measuring the proper length of the. transfer and locking the same .:whereby the transfer length will be disposed in a position whereby it may be punched, I provide a measuring disk 63 that is fixed upon .the roll 56 at one end thereof. A'notch or .recess 64 isformed in the periphery of the disk 63.

The disk 63 is circular and arrangedto turn with the roller 56. Pivoted as at 65 upon the plate 50 is a bell lever 66 having one end 67 disposed in a position whereby it Will be engaged by the inner edge of the plate 15 when the plate 15 is depressed. The other end or arm of the bell lew'er 66 is extended toward the circular measuring disk 63 and has mounted thereon a 'sl'idable locking plate 68. plate is provided at its outer end With a right angular locking lug 69 arranged to fit Within the notch or recess 64 in the peripherv of the disk 63. A pin and slot connection designated as an entirety by the nu- This locking niei'al 70 slidably connects the bell lever 66 withthelocking plate 68. A retractile of the connection designated 70 as an entirety and'serves to normally hold the outer end of the latch plate 68 in a position whereby the lug 69 will be out of engagement with the recess; 64. A retractile spring 72 is secured at its ends, to the plate 50 and intermediate portion of the rear arm. of the lever 66. This spring serves to hold the lug 17. in a position whereby the lug 69 will engage the recess 64 upon the rotation of the disk 63. A toothed wheel 73 iscarried upon one, end of the drum roller 53 and is d1sposed adjacent to the bell lever 66. This toothed Wheel 73 is fixed for rotation with the drum 53. An angularly disposed lug74 is formed onthe' inner end of the plate 68 and is adapted to engage the: teeth onthe wheel 73 and hold the drum 53 against rotation. The lug 74 locks as cle' scribed with the wheel 73 when the-latch plate 68 is caused to slide upon the bell lever 66. The latch plate 68 is slidably moved upon the lever 66 when the lug 69 engages and fits within the recess 64 and as the disk 63 is rotated the latch plate is pulled outwardly causing the lug 74 to lockingly'engage the teeth. When the latch plate 68 ispulled out wardly with relation to the bell lever 66 the 'tension of the spring 71 is exerted thus when the plate 15 isdepressed and forces downwardly the terminals 67 of the bell lever 66, the lug 69 is moved out of engagement with the recess 64: and the-spring 71 serves to move the latch plate .68 inwardly with relation to the bell lever Gdand in such a way that the lug 7 4 is moved out of engagement with the teeth on the wheel 73. The teeth on the Wheel 7 3 arearranged to permit the k operation described.

'It will be readily seenwith 1 -fefi-en@e to that the outer end of the one to be punched is positioned outwardly with respectto the ,device sufficiently to enable the operator to grasp the free end and remove the transfer after the same has been punched. a

The plate 50 is extended beyond the plate or wall 4 as at 75. The'out'er end of the plates 6 and 7 are approximately in the same position as the outer end of the wall 4.-- The side walls 2 and 3 are extended as at 76 and form in combination with the extended portion of 75 of'the plate 50 a compartment wherein is disposed the outer end of the transfer to be punched and in this connection designated 77. When the transfer has been punched the operator grasps the portion 77 and pulls the transferoutwardly until the entire transfer is adjacentto the outer edge of the extension 7.5. The transfer may thenbe torn from the rollof transfers and another transfer is positioned for operation by such action.

In operation. the operator may set the" month punch 28 as desired.by"moving' the punch into any of the slots 27 and then screwing down the knob 40. The month punch is then in a position for operation. The

same positioning of the punches 25, 34, and t is had with relation to the date and time to be punched on the transfer. This arrangementis all. set so that the operator upon the depressing of any of the transfer point punches 30 will bring about the operation of the other punches as previously described. The length of the transfer is samefrom the roll and in so doing positions I another transfer portion of the roll for. punching operation.

It will be readily seenwith reference to the foregoing description and accompanying-drawings that a large number of transfers may be issued in a comparatively short time inasmuch as the conductor has only to punch the designation'for transfer point punches and tear the transfer from the roll after pulling; it out of the device.

The adjustment of the other punches is necessary but a few times during the day.

In positioning the paper of the transfer roll the thumb screws 10 and 12 are removed permitting the bottom wall 4 and plate 50 to be letdown, the same being free with relation to the side walls 2 and 3, or the plates 6, 7 and 15 which are connected with each other and hinged to the cover 59 as at 60 may be swung up allowing the operator to properly position .the free end of the transfer roll. The hinge pin at the hinge (30 may be removed and the perforating mechanism as a unit consisting of the plates 6, 7 and 15 and cooperating parts may be removed.

It will be readily seen with reference to the foregoing description and accompanying drawings that I have provided a simple and inexpensive device which will save a great deal of time and labor in issuing transfer's and enable a inoreeflicient handling of street cars in general.

In reduction to practice, :I have found that the form of my invention, illustrated in the-drawings and referred to in the above description, as the preferred embodiment, is the most eflicient and practical; yet realizing that theconditions concurrent With the adoption of my device will necessarily vary, I desiretoemphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, whenrequired, without sacrificing any of the advantages of. my invention, as defined in the appended claims.
